Explanation Given info: The two charged particles are located on the x − axis that has a value of + Q located at position x = a and the other charge that is an unknown charge located at a position of x = + 3 a . electric field produced by these charges at the origin is 2 K Q a 2 Let the unknown charge be Q ' . The formula to calculate the electrical field is, E = K Q r 2 Here, K is the constant . Q is the external charge. r is the distance between external charge and test charge.. The electric field possessed by the first charge is E 1 at distance x = a is, E 1 = K Q a 2 = K Q a 2 Here, K is the constant . Q is the first point charge. a is the distance between external charge and test charge. The electric field possessed by the second charge is E 2 at distance x = 3 a is, E 2 = K Q ' ( 3 a ) 2 = K Q ' 9 a 2 Here, K is the constant. Q ' is the first point charge. 3 a is the distance. Let the unknown charge is negative then the net electric field is the sum of individual field. The net electric field produced by two charges at the origin is, E = E 1 + E 2 Substitute K Q a 2 for E 1 , K Q ' 9 a 2 for E 2 , and 2 K Q a 2 for E in above expression
